INTERNAL-COMBUSTION ENGINE.

. To all whom it may concern:

Be it known that I,"LOUIS S. MORRIS, a citizen of the United States, residing at Bridgeport,- in the county of Fairfield and State of Connecticut, have invented a certain new and useful Internal-Combustion Engine, of which the following is a specification.

My invention relates to internal combustion engines of the rotary type wherein there is provided a rotor carrying sliding pistons which, acting in conjunction with the rotor and stator, will draw inthe explosive mixture, compress it and, on the explosion of the charge, the rotor will be ro-,

tated and draw in and compress new charges which, when ignited will continue the operation. The particular type of engine to which my present improvement more particularly relates, is disclosed in my co-pending application for patent filed March 31, 1914, and numbered serially 828,536.

The object of my invention is to simplify the construction of the device by eliminat ing, to a large extent, reciprocating parts.

Another object is to provide means for cooling the rotor.

A further object is toprovide means for effecting a supplemental scavenging of the device. 4 I

These and further objects will appear from the following specification and accompanying drawingstaken together or separately.

- My invention is illustrated in the following drawings in which the same parts are designated by corresponding reference characters in all the figures. I

Figure 1, is a sideelevation of my improved engine.-

Fig. 2, is a transverse section of the same taken on the line 2-- 2 of Fig. 3.

Fig. 3, is a longitudinal section taken on the line 3-3 of Fig. 2.

Fig. 4, is a detail sectional view through one of the piston slides, and Fig. 5, 1s a detail, section taken on the line 5-5 of Fig. 2.

A stationary casing or stator is employed and may besecurely fastened to a floor or other foundation. The stator is composed of an annular body 1 and side members 2, 2. The body is constructed of anouter and an inner shell, and the Space between the shells;

when closed by the side members, forms a water jacket as is usual. Each side member 1s provided witha bearing 3 for the sup"- port of the shaft 4 ofthe engine to which .is rigidly secured a rotor R. The bearings are equipped with glands 5, 5 to prevent leakage along the shaft. The bore of the stator is not cylindrical in its entirety butis, in the embodiment of the invention chosen for illustration, composed. of four cylindrical segments 6 of the same diameter as the rotor, and four eccentric portions 7 each having a maximum radius somewhat greater than that of the rotor.v These eccentric portions are disposed around the bore of the body at 90 degrees apart and'each, when the rotor is in position, forms a chamber gradually increaslng in depth from one edge at part6 to the maximum depth, then extending concentrlc with the part 6, then gradually decreasing in depth to the nearer edge of the ad acent part 6.

The body 1 is provided with two (liar.

, bore of-the rotor and are forced into intimate engagement with the periphery of the rotor by the pressure of leakage gas behind them.

trated I show two rotary transfer valves 11,

In the embodiment of the invention illus-J 11, diametrically opposite each other, each carried in a valve casing12- forming part of the body and each is spaced approximately 90'. degrees from the inletand exhaust ports between which it is situated' The valve comprises a cylindrical body having four 'equally spaced pockets12 around its periphery. Each valve casing 12 is provided with an inlet port 14.- and an outlet port 15 and between these ports, 1n the bore of" the stator, is a segment w1th1 n the boundaries of which are PaCkHIiI-fitrIPS IG g str1p s 10. .The valve inlet port 14 oflers communlcation between one ofthe spaces or pockets 7, and the valve casing, and the valve exhaus't port 15 is between the valvecasing and another space or pocket 7, Each valve- 35 seated in the pocket 28. Between the body 45 i to be forced into intimate contact with the I and hasa stud which engages a curved slot stem 17 is'provided, outside the casing, with a spiral'gear 18 which meshes with a spiral gear 19 carried on a shaft .20. .This shaft at its center is geared to the engine shaft 4- through spiral. gears 21 and 22. The gears are so proportioned as to rotate the w alves 11 at twice the speed of the engine shaft.

Each valve is provided with conduits through which lubricating oil may be forced to the periphery of the valve.

*If desired the stator may be provided.

with channels 23 by means of which the valve pockets 13 may be scavenged.

Adjacent to each valve exhaust port 15, I provide a spark plug 24 or other charge igniting device.

The rotor R fits within the bore of'the stator and its periphery forms a close working contactwith the segments 6 and strips 10 and 16, and, as shownin my application for patent above referredto, is provided with a plurality, in the present embodiment eight, of piston slides 25 each carried in a radial slot 26 extending inward from the periphery of the rotor.

tirelyacross the face of the rotor. The bottom of each slot is provided with a cylindrical bore 27 communicating with a pocket 28 in the rotor. I

The piston slide 25 is composed of a rectangular body fitting and sliding within a slot 26. The inner side of the bodyis provided with a shank 29 which passes through the bore 27 and is engaged by a spring 30 of the piston slide 25 and the slot 26 Iprovide bafile grooves to prevent leakage at that point and I also have baflie grooves between the shank 29 and the bore 27 for the same purpose. y i

The outer face of each piston slide is provided with a semi-cylindrical channel 31 in which is seated a semi-cylindrical face block 32. 'The outer face of the block is adapted bore of the stator.

In order to prevent the block 32 from being thrown from its socket by centrifugal action when the engine is running, I provlde the following mechanism.- Each end of the piston shde is recessed to receive-a link 33 which is" held against longitudinal displace-.

mentby a pin 34 in one end of the link. The other end of the link lies within a segmental recess 35 in the end of the block 32 36 in the bottom of the recess. This construction, while'it prevents displacement of the block, still permits it to rock in the channel as its outer face follows the contour of the bore of the stator.

Disposed within the stator at each side thereof is an annular cheek plate 37 the opening in which is a true cylinder and the The slots 26 are rectangular in cross section and extend enouter periphery is shaped to the same configuration as the bore of the stator; The side plates 2 carry set screws 38 by means of which the cheek plates may be adjusted relatively to the side plates and to the rotor. The rotor is provided at each side with an annular recess 39 in which the cheek plates rest. The bottom of each recess has a cir cumferential groove which carries a ring 40 to prevent leakage between the cheek plates duct 44 is a return duct 45-which offers com- I munication between the chamber and an outdoes not communicate with the inner part of the chamber but its opening is near the outer periphery of the chamber. The outlet passage 46 connects with an'annularspace 47 in the same fitting in which the space 43 is located. The spaces 43 and 47 are separated from each other by a water tight pack:

'let passage 46 in the shaft 4. The duct 45 ing and the fitting is suitably packed to prevent leakage at its ends.

The operation of my improved device is as follows:

With the parts in the position shown in Fig. 2 the rotor will be turned in the clock wise direction by any well known means, and.

as the piston slides nearest the inlets 8 are moved, the spaces behind them are filled with the proper mixture of gas and air which flows in to fill the "spaces left by the movements of the slides. This mixture will remain uncompressed in the space 7 behmd the slide until the next slide passes the inlet 8 and the first slide passes the strips 16. The charge will nowbe compressed, on account of the diminishing in size of thespace 7, and forced into the valve inlet port 14. From the port 14 the compressed mlxture will enter a pocket'13 in the transfer valve which is also traveling in'the clock-wise direction and when the pocket containing the compressed charge comes into. communica- -tion with the valve outlet port 15 the charge ,will be exploded by means of the sparker 24 and the expanded gas will act on the rear of. the first piston slide, which in the meantime has passed the port 14, and drive it ahead. The products. of combustlon will acted on by the charge compressed by the piston slide following it. The strips 16 will prevent the exploding charge from exerting be driven from the exhaust 9 bythe second piston slide which follows the first and 1s pressure rearwardlyand the strips 10 will prevent the products of combustion from mixing with uncompressed gas at the inlet.

Should it be found necessary to scavenge the pockets in the transfer valve, the same may be accomplished by passing a current of air or other fluid through the ducts 23 by any suitable device working in time with the engine.

The cooling ofthe rotor is accomplished as follows: Cold water enters the passage 42 and flows out to the chamber 41. The centrifugal force of the rotor will tend to force the water outward and it will accumulate in the chamber 41 until such chamber is filled, be driven down the duct 45 against the centrifugal force exerted therein and out of the shaft through the duct 46.

In accordance with the provisions of the patent statute I have now described my invention together with the apparatus which I consider to represent the best embodiment that the invention disclosed in the drawings is merely illustrative and that the invention may be carried out in other ways without departing from the spirit of my invention.

Having now described my invention, what I claim as new and desire to secure by Letters Patent is, I

An internal combustion engine comprisingYa. stator and a rotor, a fuel inlet, a spring pressed piston slide, an oscillatory face block carried by the piston slide, a plurality of links for securing the block to the slide, and recesses in the block to permit the block to oscillate.

This specification signed and witnessed this 17th day of July, 1914.
